“…According to [5], for a two-particle final state the near-threshold behaviour of the reaction depends solely on the asymptotic form of the continuum wave function. The Wigner threshold law is only the first term of a power series expansion in the electron momentum, and deviation appears when higher-order terms become important [6]. The range of validity of the Wigner law for negative ions is affected by short-range interactions such as induced polarization, static multipole moments of the residual atom, and the existence of nearby Feshbach resonances [7].…”

The cross section of dipole-magnetic photodisintegration of the negative hydrogen ion has been calculated within the framework of an effective-range theory. The dipole-magnetic cross section of photodetachment within the very narrow range of energy near the process threshold dominates over the dipole-electric one. It has been shown that in ultracold hydrogen plasma at temperatures below kT=3.29•10 -4 K the dipole-magnetic photo-recombination becomes a main mechanism of electron capture by hydrogen atoms.

Inner-shell photodetachment of Na− near the L-edge threshold was investigated using the R-matrix method. Significant structure was found in the cross section, and this structure is shown to be related to the complicated correlated electron dynamics endemic in negative ions. Comparison with experiment suggests that the absolute values of the measured cross section might be too small by a factor of two.
